Can I have a gastroscopy right after finishing quadruple therapy?

Generally speaking, a gastroscopy can be performed immediately after completing quadruple therapy. The detailed analysis is as follows:

Quadruple therapy is a standard treatment regimen for Helicobacter pylori infection, consisting of a proton pump inhibitor, two antibiotics, and a gastric mucosal protective agent. Gastroscopy is an endoscopic procedure used to examine lesions in the esophagus, stomach, and duodenum. It helps physicians diagnose and treat various gastrointestinal conditions such as gastritis, gastric ulcers, and esophagitis. During gastroscopy, a flexible endoscope is inserted through the mouth, passing through the esophagus into the stomach and duodenum. A camera on the endoscope allows visualization of the gastrointestinal tract's interior, enabling biopsy sampling or therapeutic interventions. Having just completed quadruple therapy does not affect the accuracy of the gastroscopy results or interfere with treatment outcomes; therefore, gastroscopy can be safely performed immediately after finishing the quadruple therapy.

It is recommended that patients follow medical guidance regarding fasting and abstaining from fluids before undergoing gastroscopy to avoid affecting the examination results.
